I  have to say that i’m realy stupid enough do make such lot of mistakes about the preprocessing, anyway I would like to write dowm these bug that waste me lot of time.

1. Please remove bad channels before you do common average

2. Resting state signals need to segemented in to short length and you could not average them

4.Resting state could be combined tegether when do time frequency analysis

5.learn to control the redefinetrail function which should be very improtant

6. for the bad channels when you remove , you need to interprolate and repair them

7. keeptrials=’yes’ when timelock and frequency analysis which could be directly used for timelock statistic or frequencystatistic;
